Abstract

1,111,629. Echo ranging using electromagnetic waves. CHEVRON RESEARCH CO. 13 Sept., 1966, No. 40955/66. Heading H4D. In order to enable accurate positioning of an oil well bore 12 into a sedimentary formation with respect to a salt dome 10, the interface of the salt dome and adjacent sedimentary formations is determined by echo ranging utilizing radio or light waves from a probe 40 in a bore hole 30 drilled into the salt dome. Radar.-The aerial in the probe may be omnidirectional in the horizontal plane or directional with continuous rotation. Scanning in elevation may be added. The radar may be pulse-echo or F.M. type, the latter being preferred for short ranges. The preferred radio frequency is in the range 10<SP>6</SP> to 10<SP>10</SP> c/s. The probe incorporates a radome. On the surface a type A display 60 is photographed together with aerial azimuth and probe depth. The probe aerial may be of the Yogi type and collapsible, Fig. 4 (not shown) or may incorporate a parabolic reflector, Fig. 3 (not shown). The fluid in the bore hole may be chosen to afford efficient coupling to the salt dome. Light echo ranging.-The preferred frequency is in the range 2 x 10<SP>13</SP> to 10<SP>15</SP> c/s. from a pulsed laser, Fig. 6 (not shown). Directional scanning is by rotating inclined mirrors.
